La3d 是 X 射线光电子能谱仪 (XPS) 的主要分析区域，但 La4p 和 La4d 区域可有助于对镧化合物进行化学状态归属。 La3d 区域具有明显分离的自旋轨道分裂峰。 每个自旋轨道分裂峰通过多重劈裂进一步分裂。 例如，即使只有一个化学状态的纯 La (OH) 3 样品，其 La3d 谱图有四个可见峰。 多重劈裂的程度以及每个多重劈裂峰的强度比都可以辅助化学态分析。 测试分析 La4p 区域也有助于化学态归属，例如，区分 La 2 O 3 和 La (OH) 3 。 La 2 O 3 形式的 O1s 结合能通常较低， …

Lanthanum X-ray photoelectron spectra, lanthanum electron configuration, and other elemental information. La3d is the primary XPS region, but La4p and La4d regions can help assign the chemistry of lanthanum compounds. La3d region has well-separated spin-orbit components. Each spin-orbit component is further split by multiplet splitting.

The XPS spectra of La(3d) core level for 9LZO are deconvoluted into two peaks located at the B.E. of 836.6 and 853.3 eV, corresponding to La 3+ (3d 5/2 ) and La 3+ (3d 3/2 ), respectively (Fig. 6...

We report the hydrogen barrier performance of sputtered La2O3 thin films for the device stability of amorphous indium–gallium–zinc–oxide (a-IGZO) thin-film transistors (TFTs). Hydrogen acts as a...

Fig. 12h shows the XPS spectra of La3d on the worn surface. The new peaks at 835.1 (peak 1) and 836.1 (peak 2) eV after adding nano-La(OH) 3 /RGO composites to the diesel engine oil belong to...

你在870-830 ev区间 测量的是la 的3d 层的电子的binding energy，3d 电子有两个峰， 3d5/2 和3d3/2，对la来说， 这两个峰位相差～16.6-16.9 ev。 你所描述的峰位置 （835.8～835.9 ev）应该是la3d 5/2峰，但无法确定la处于什么氧化态，要想回答这个问题，你要：1， calibrate （这个怎么说， 标定？ ）你的实验数据；这个非常重要，否测可以得出任何结果；2， 拟合实验数据；2， 查找文献； 可以到nist 的xps数据库查找： http:///xps/default.aspx3， 测量o1s （如果可行）， …

2023年5月5日 · The purity and surface morphology of the as-grown La2O3 films, which possessed a constant growth rate of ~0.4 Å/cycle at 250–280 °C, were confirmed by XPS, SEM, and AFM. The results show that La(thd)3-DMEA is a suitable precursor for the atomic layer deposition of La2O3 film.

2023年12月1日 · The local XPS spectra of La3d and Ni2p are illustrated in Fig. 7 (b,f), showing complex features due to spin–orbit interaction and multiplet splitting. The XPS spectrum of La3d is divide into two peaks, 3d 5/2 and 3d 3/2 , located at 834.68 and 851.48 eV for x = 0, respectively, and at 834.58 and 851.38 eV for x = 0.025, respectively, along ...
